The product packaging box adopts a minimalist design style, with UGREEN printed on the frontLvlianBrand, product name in Chinese and English, and appearance, with100WMax logo design, indicating product support100WFast charging.
A bilingual version with product introduction, specifications and business information printed on the back.
Product information close-up on the packaging box, the data line supports forward and backward blind insertion, the transmission rate is 480Mbps (MAX), and it supports 5A charging and the maximum PD100WOutput.
The package contains data cable and product certificate.
Lvlian 100W fast charging data line is a braided line, with black as the main color, and silver gray at both ends. Lvlian has a very classic design style.
Both ends of the wire material are made of metal shell, and the surface is sprayed with silver gray metallic paint to improve the texture. The front side of the wire material is carved with UGREEN brand.

The measured length of Lvlian 100W fast charging data line is about 150cm.
The weight is about 47g.
Using ChargeLAB POWER-Z KM003C, it is measured that the cable is equipped with an E-Marker chip, with power transmission capacity of 20V5A and data transmission capacity of USB 2.0.
In terms of voltage drop test, the test data results of wire rod at 11 gears are shown in the table above.
The histogram is drawn. It can be clearly seen that the gear with the largest difference in pressure drop is 0.68V of 20V5A, and the gear with the lowest difference is 0.13V of 9/12/15V1A.
Finally, use this data cable with Aohi 140W charger to charge Apple MacBook Pro. The measured input power of the notebook interface terminal is 19.38V 4.55A 88.25W, and the 20V5A PD fast charge is successfully enabled.
Disassembly of Lvlian 100W fast charging data cable
After watching the appearance and testing of the USB-C data cable of Lvlian, we will disassemble it and take a look at its workmanship and materials.
First, cut the outer aluminum alloy shell of the plug, and the inside is filled with injection molding.
Clean the outer layer of injection molding, and spot weld the USB-C plug to the stainless steel shell.
The stainless steel housing is spot welded to the USB-C plug.
Close up of the harness structure at the rear of the housing.
Remove the stainless steel housing, and fill the black injection molding support insulation between the plug PCB board and the housing.
The cable shielding layer is wrapped with copper foil to prevent looseness.
Clean the filled black injection molding, and weld the E-Marker chip on one side of the small board.
The small plate is welded with red positive power core, USB2.0 data core, CC core, Vconn core and negative core.
The other side is welded with positive and negative wire cores and E-Marker chips.E-Marker chip screen printing 332A is Huinengtai HUSB332A, and HUSB332A is USB Type-C electronic label chip (USB eMarker).It also supports USB Type-C specification 2.0, USB Power Delivery specification 3.0, USB4 specification and Thunderbolt 3 specification, and supports USB PD3.1 EPR extended power range.It has passed the certification of USB-IF Association, TID No.: 4324.
Continue to disassemble the plug at the other end, and cut the outer aluminum alloy shell of the plug.
The interior is also filled with glue.
Stainless steel shell is used inside the glue injection.
The stainless steel housing is spot welded to the USB-C plug.
Close up of the harness structure at the rear of the housing.
Remove the stainless steel housing, and fill the black injection molding support insulation between the plug PCB board and the housing.
Clean the filled black injection molding, and the terminal connection board is inside.
The small plate is welded with red positive power core, USB2.0 data core, CC core, Vconn core and negative core.
The other side is welded with positive and negative pole cores.
Cut the data cable to observe the section. The outermost black braided cable is twisted, and the cut cable is not loose.Six cores with insulating skin can be seen on the cross section, of which two red cores are positive power cores, blue cores are CC cores, yellow cores are VCONN cores, white green cores are USB2.0 cores, and negative cores are five bare cores.
Inside the black braid is a black TPE cable.
Cut the outer skin of the cable, and the inside is a woven shielding mesh.
Below the shielding mesh is a layer of shielding aluminum foil, which tightly wraps the inner core of the cable.
Close up of power core and data core inside the cable.
All the cables are disassembled for a glance, which are in turn woven jacket, plastic sheath, metal shielding mesh, shielding aluminum foil, power cable core and data cable core.Now we will begin to introduce the core design inside the cable in detail.
The two red positive pole power cores are tinned copper wires with anti pulling wires inside.
For the data line used for USB2.0 transmission, the green D+core has an anti pull wire inside.
White D-wire core also has anti stay wire inside.
Close up of blue CC wire core, with anti stay wire inside.
Close up of yellow Vconn wire core, with anti pulling wire inside.
Five bare wire cores are used for negative pole power transmission, and anti pulling wire is set inside.
Close up of four anti stay wires filled in the cable.
Take a look at all of them and have a family photo.
Disassembly summary of charging head network
The USB-C data cable of Lulian is 1.5 meters long and adopts black high-density nylon braided wire body, which is durable and durable, and has a good feel.Both ends of the cable are equipped with aluminum alloy shells, and the cable and the terminal are equipped with net tail for enhanced protection.The measured cable supports 100W power transmission, which is suitable for notebook computers, high-power mobile power supplies and mobile phone fast charging.
The charging head network learned through disassembly that the USB-C plug of the data line of Lvlian uses an aluminum alloy shell, and the internal plug is spot welded to fix the stainless steel shell, which is filled with injection molding.The small terminal board is welded with Huinengtai HUSB332A E-Marker chip to mark the cable capacity.The cable adopts thickened conductor, and is equipped with metal shielding mesh and shielding aluminum foil.
